Frostbike: Orange Seal Goes Subzero, Offers New Cold Weather Sealant and Fat bike Tubeless Kits
Yes, more fatbike (and cold weather) stuff. What do you expect from a trade show that was held in a city with feet, not inches, of snow on the ground? There has been a lot of experimentation going around with tubeless fatbikes, and why not? All of the benefits of tubeless are supersized on fatbike – much lower rolling resistance, no flats, and even more traction! While the benefits are clear, the methods are not. Much like the early days of mountain bike tubeless, fat bike tubeless is just starting to get sorted out. Orange Seal is one company leading the charge with their Fat Bike tubeless conversion kits, and their new Sub-Zero sealant. Many in colder climates have been mixing their Stan’s Sealant with antifreeze or other homebrew methods to keep the sealant working below freezing, but Orange Seal takes the guess work out of the equation with their new cold weather specific goo.
Rated to work down to -20-30ºf, Orange Seal Sub Zero will do the trick whether you’re fat biking or just riding your mountain bike/commuter/whatever in the extreme cold. Sealant is sold in 8oz bottles for $14.49 which is just enough for two fatbike tires. Orange Seal said Borealis has been using the Subzero sealant on their Carbondale rims with great results at 40z per tire.
Sub Zero sealant is also available in their Fat Bike tubeless conversion kits which include two 32mm valve stems, rim tape, and an 8 oz bottle of sealant. Kits are offered in both 45mm and 75mm tape widths to fit a number of fatbike rims. Fat Bike kits retail from $59.99 to $66.99 depending on the sealant and width.
